FULL DESCRIPTION / HOW TO
This one is difficult because of the time limit you have to complete the mission. You need to take out 3 bases quickly. The best way to do this is the way I did it but there is some luck involved with this as the AI can do different things each time. It took me 2 attempts after getting the first one 4 seconds slow. Just remember to push as soon as you have 1 offensive unit to damage the right base early on and set the rally point of the war factory to follow your attacks, and support them with bullfrogs to stop the sky wings from taking you out.
